Subasic vs Thompson

This market covers a first-round tennis match between Alana Subasic and Belle Thompson at the ITF W15 Brisbane event, originally scheduled for July 16, 2026. Each platform's headline market resolves to the player who advances, with variations for retirements, walkovers, and cancellations spelled out in the individual rulebooks. The bulk of the activity sits on Kalshi, which drove the roughly $1.12M in total volume, while Polymarket and Azuro carried only minimal liquidity on the moneyline. The pricing across platforms is unusually inconsistent. Kalshi has Belle Thompson at 99.0% and Alana Subasic at just 1.0%, effectively treating the match as resolved. Polymarket sits at Thompson 32.5% and Subasic 67.5%, while Azuro flips the picture further with Subasic at 84.8% and Thompson at 22.0%. That produces a cross-platform spread of 66.5 percentage points on the same outcome, which almost certainly reflects the closed status of the event and stale or thinly traded quotes on Polymarket and Azuro rather than genuine disagreement about who wins. The takeaway: Kalshi's near-certain 99.0% price on Thompson is the only figure supported by meaningful volume, and the wide spread against Polymarket and Azuro is a liquidity artefact rather than a live market signal.
